I’d give it at least 4-6 months before assuming service will settle into a rhythm that works well for most. I’d also assume that the younger and louder ambience will continue.
That being said, I’m entertained by the poor TripAdvisor reviews that complain about $18 drinks and pricey spa treatments for a 4 star hotel in tony Newport Beach—let alone one right on the harbor. I think a lot of Midwestern clueless people don’t know what Newport Beach is actually like or how much more expensive the even better 5 star resorts can be!
